GRI 303: Water 2016
Introduction
A. Overview
This Standard is part of the set of GRI Sustainability
Reporting Standards (GRI Standards). These Standards
are designed to be used by organizations to report
about their impacts on the economy, the environment,
and society.
The GRI Standards are structured as a set of
interrelated, modular standards. The full set can be
downloaded at www.globalreporting.org/standards/.
There are three universal Standards that apply to every
organization preparing a sustainability report:
GRI 101: Foundation
GRI 102: General Disclosures
GRI 103: Management Approach

GRI 303: Water is a topic-specific GRI Standard
in the 300 series (Environmental topics).
There are two basic approaches for using the GRI
Standards. For each way of using the Standards there
is a corresponding claim, or statement of use, which
an organization is required to include in any published
materials.
1. T
he GRI Standards can be used as a set to prepare
a sustainability report that is in accordance with
the Standards. There are two options for preparing
a report in accordance (Core or Comprehensive),
depending on the extent of disclosures included in
the report.
An organization preparing a report in accordance
with the GRI Standards uses this Standard,
GRI 303: Water, if this is one of its material topics.
Universal
Standards
To report contextual
information about
an organization
Each topic Standard includes disclosures specific to
that topic, and is designed to be used together with
GRI 103: Management Approach, which is used to
report the management approach for the topic.
B. Using the GRI Standards and making claims
GRI 101: Foundation is the starting point for using
the GRI Standards. It has essential information
on how to use and reference the Standards.
102
An organization then selects from the set of topicspecific GRI Standards for reporting on its material
topics. These Standards are organized into three series:
200 (Economic topics), 300 (Environmental topics) and
400 (Social topics).
300
2. S elected GRI Standards, or parts of their content,
can also be used to report specific information,
without preparing a report in accordance with
the Standards. Any published materials that use
the GRI Standards in this way are to include a
‘GRI-referenced’ claim.
See Section 3 of GRI 101: Foundation for more
information on how to use the GRI Standards,
and the specific claims that organizations are
required to include in any published materials.

C. Requirements, recommendations and guidance
The GRI Standards include:
Requirements. These are mandatory instructions.
In the text, requirements are presented in bold font
and indicated with the word ‘shall’. Requirements are
to be read in the context of recommendations and
guidance; however, an organization is not required to
comply with recommendations or guidance in order
to claim that a report has been prepared in accordance
with the Standards.
Recommendations. These are cases where a particular
course of action is encouraged, but not required. In the
text, the word ‘should’ indicates a recommendation.
Guidance. These sections include background
information, explanations and examples to help
organizations better understand the requirements.
An organization is required to comply with all applicable
requirements in order to claim that its report has been
prepared in accordance with the GRI Standards. See
GRI 101: Foundation for more information.
D. Background context
In the context of the GRI Standards, the environmental
dimension of sustainability concerns an organization’s
impacts on living and non-living natural systems, including
land, air, water and ecosystems.
GRI 303 addresses the topic of water.
Access to fresh water is essential for human life and
wellbeing, and is recognized by the United Nations
as a human right. An organization can impact water
resources through its withdrawal and consumption
of water.
Withdrawals from a water system can affect the
environment by lowering the water table, reducing the
volume of water available for use, or otherwise altering
the ability of an ecosystem to perform its functions.
Such changes have wider impacts on the quality of life
in the area, including economic and social consequences;
and consequences for the local communities or
indigenous peoples for whom the water source is
important.
The disclosures in this Standard can provide information
about an organization’s impacts related to water, and
how it manages them.
Additional disclosures that relate to this topic can also
be found in:

GRI 306: Effluents and Waste
GRI 303: Water 2016
GRI 303:
Water
This Standard includes disclosures on the management approach and topic-specific
disclosures. These are set out in the Standard as follows:
•Management approach disclosures (this section references GRI 103)
• Disclosure 303-1 Water withdrawal by source
•Disclosure 303-2 Water sources significantly affected by withdrawal of water
• Disclosure 303-3 Water recycled and reused
1. Management approach disclosures
Management approach disclosures are a narrative explanation of how an organization manages a material topic,
the associated impacts, and stakeholders’ reasonable expectations and interests. Any organization that claims its
report has been prepared in accordance with the GRI Standards is required to report on its management approach
for every material topic, as well as reporting topic-specific disclosures for those topics.
Therefore, this topic-specific Standard is designed to be used together with GRI 103: Management Approach in order
to provide full disclosure of the organization’s impacts. GRI 103 specifies how to report on the management approach
and what information to provide.
Reporting requirements
1.1 The reporting organization shall report its management approach for water using
GRI 103: Management Approach.
GRI 303: Water 2016

2. Topic-specific disclosures
Disclosure 303-1
Water withdrawal by source
Reporting requirements
The reporting organization shall report the following information:
a. Total volume of water withdrawn, with a breakdown by the following sources:
Disclosure
303-1
i. Surface water, including water from wetlands, rivers, lakes, and oceans;
ii. Ground water;
iii. Rainwater collected directly and stored by the organization;
iv. Waste water from another organization;
v. Municipal water supplies or other public or private water utilities.
b. Standards, methodologies, and assumptions used.
Reporting recommendations
2.1 When compiling the information specified in Disclosure 303-1, the reporting organization should:
2.1.1 include the abstraction of cooling water;
2.1.2 report whether these calculations are estimated, modelled, or sourced from direct measurements;
2.1.3 if estimation or modelling has been used, report the estimation or modelling methods.
Guidance

Guidance for Disclosure 303-1
Background
This disclosure can include water withdrawn either
directly by the organization or through intermediaries,
such as water utilities.
Reporting the total volume of water withdrawn by
source contributes to an understanding of the overall
scale of potential impacts and risks associated with an
organization’s water use. The total volume withdrawn
provides an indication of the organization’s relative
size and importance as a user of water, and provides
a baseline figure for other calculations relating to
efficiency and use.
GRI 303: Water 2016
Disclosure 303-2
Water sources significantly affected by withdrawal of water
Reporting requirements
The reporting organization shall report the following information:
a. Total number of water sources significantly affected by withdrawal by type:
Disclosure
303-2
i. Size of the water source;
ii. Whether the source is designated as a nationally or internationally protected area;
iii.Biodiversity value (such as species diversity and endemism, and total number of
protected species);
iv. Value or importance of the water source to local communities and indigenous peoples.
b. Standards, methodologies, and assumptions used.
2.2When compiling the information specified in Disclosure 303-2, the reporting organization
shall report water sources significantly affected by withdrawal that meet one or more of the
following criteria:
2.2.1 Withdrawals that account for an average of five percent or more of the annual average
volume of the water body;
2.2.2 Withdrawals from water bodies that are recognized by professionals to be particularly
sensitive due to their relative size, function, or status as a rare, threatened, or endangered
system, or that support a particular endangered species of plant or animal;
2.2.3 Any withdrawal from a wetland listed in the Ramsar Convention or any other nationally
or internationally proclaimed conservation area, regardless of the rate of withdrawal;
2.2.4 The water source has been identified as having high biodiversity value, such as species
diversity and endemism, or total number of protected species;
2.2.5 The water source has been identified as having a high value or importance to local
communities and indigenous peoples.
Reporting recommendations
2.3 When compiling the information specified in Disclosure 303-2, the reporting organization should report the
original water body or source, if the water is provided by municipal water supplies or other public or private
water utilities.
Guidance
See references 1 and 3 in the References section.
GRI 303: Water 2016

Disclosure 303-3
Water recycled and reused
Reporting requirements
The reporting organization shall report the following information:
a. Total volume of water recycled and reused by the organization.
Disclosure
303-3
b. Total volume of water recycled and reused as a percentage of the total water withdrawal
as specified in Disclosure 303-1.
c. Standards, methodologies, and assumptions used.
2.4 When compiling the information specified in Disclosure 303-3, the reporting organization shall
include grey water, i.e., collected rainwater and wastewater generated by household processes,
such as washing dishes, laundry, and bathing.
Reporting recommendations
2.5 When compiling the information specified in Disclosure 303-3, the reporting organization should:
2.5.1
report if water or flow meters do not exist and estimation by modeling is required;
2.5.2calculate the volume of recycled/reused water based on the volume of water demand satisfied
by recycled/reused water, rather than by further withdrawals.
Guidance
Guidance for Disclosure 303-3
Background
This disclosure measures both water treated prior to
reuse and water not treated prior to reuse.
The rate of water reuse and recycling is a measure
of efficiency and demonstrates the success of an
organization in reducing total water withdrawals and
discharges. Increased reuse and recycling can reduce
water consumption, treatment, and disposal costs.
Reducing water consumption over time through reuse
and recycling also contributes to local, national, or
regional goals for managing water supplies.
Guidance for clause 2.5.2
For example, if an organization has a production cycle
that requires 20 m3 of water per cycle, the organization
withdraws 20 m3 of water for one production process
cycle and reuses it for an additional three cycles, then
the total volume of water recycled and reused for that
process is 60 m3.
